Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Limit time that researchers/tourists are allowed to spend with habituated animals One controlled study in Indonesia found that reintroduced Sumatran orangutans that spent limited time with caretakers acted more similar to wild orangutans than orangutans that spend more time with caretakers, alongside other interventions. One before-and-after study in Rwanda, Uganda and the Democratic Republic of Congo found that numbers of mountain gorillas increased by 168% over 41 years while being visited by researchers and visitors during a restricted amount of time, alongside other interventions.

Both studies were in the USA. COMMUNITY RESPONSE (1 STUDIES) Richness/diversity (1 studies): One replicated, site comparison study found that restricting access of off-road vehicles and sheep had mixed effects on lizard species richness. POPULATION RESPONSE (2 STUDIES) Abundance (2 studies): One of two replicated, site comparison studies (including one randomized study) in the USA found that areas where off-road vehicles were completely excluded using fencing that also excluded livestock grazing had higher densities of Agassiz’s desert tortoises compared to areas with some restrictions or no restrictions. The other study found that restricting off-road vehicle and sheep access had mixed effects on lizard abundance. Survival (1 study): One replicated, randomized, site comparison study in the USA found that in areas where off-road vehicles were completely excluded, death rates of Agassiz’s desert tortoises were lower than in areas with some restrictions or no restrictions.

This study was in Brazil. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Abundance (1 study): One site comparison study in Brazil found that in areas where a fishing agreement was implemented that involved limiting the use of gill nets along with a wider suit of measures had more river turtles than areas that did not implement the agreement.
